[Backport] BashOperator: Execute templated bash script as file
Backport of #42783 to Airflow 2.
When the BashOperator fails to write the rendered Jinja into a new file, it warns the user to add "write" and "execute" permissions in the working directory before Airflow 3; and fallback to the 2.10.2 behavior: executing the content of the bash script as inline command.
